CNM Jitsi (formerly known as CNM Talkware; hereinafter, the Soft) is a CNM stable app built with Jitsi. The Soft is the CNM app that is configured to power CNM Talk, TalkHandsOn, or TalkNext service of CNMCyber. The App is based on commercial off-the-shelf (COTS) webconferencing software, Jitsi. The App is a part of CNM Cloud.

Challenges

Load balancer

We are looking for solutions to implement a load balancer in CNM Jitsi. We are considering several approaches and want to find the best one: 1) put the Jibri on separate bare metals, 2) put the Jitsi Videobridge on separate bare metals, 3) put the Jitsi Meet on separate bare metals, 4) your suggestion. Now all the apps/elements of the Jitsi that were installed along with the Jitsi meet are installed on the same bare metal.

Connectivity issues

There are often problems with the connection. One participant cannot hear the other. There is also a problem that periodically, about once every 10 minutes, participants stop seeing and hearing each other, it lasts about a minute and then the connection returns.

LDAP integration

We have authorization from LDAP. But it would be good if the login of a registered user was automatically displayed as a name in the conference.

Product specification

The Product specifications are:
What distinguishes CNM Jitsi from Jitsi:
  1. CNM Jitsi has LDAP authentication. To do this, we made a change to the configuration file, where we disabled internal authorization and enabled LDAP.
  2. CNM Jitsi instances are installed on CNM Bureau Farm that features high availability (or HA) powered by CNM ProxmoxVE.
  3. CNM Jitsi does not use the Jigasi (Jitsi Gateway to SIP) - server-side application that allows regular SIP clients to join Jitsi Meet conferences. More about standard Jitsi structure - Jitsi.

Software instances

The software instance that powers core, hands-on training, and experiential systems.

Security

Malware protection

Previously, CNM Cloud developers struggled with the viruses, so an effective anti-virus strategy must be found -- what was the solution?

Standing operating procedures

Standing operating procedure

Monitoring process

Monitoring is done in Nagios, not on CNM Jitsi. Read more: CNM Nagios.

Backup

Usually, the main backup is done on the farm, not on CNM Jitsi. So you can read more about backup on CNM Bureau Farm.

Snapshot

Snapshots are made by hand on the farm, not on CNM Jitsi. Read more: CNM Bureau Farm.

Customization

To customize certain elements of Jitsi, you should:
  1. open the server where Jiti is installed in Terminal;
  2. open the Midnight Commander by using the command root@jitsi:/home/jitsi# mc;
  3. open catalog /usr (click /.. -> /.. -> /usr);
  4. open catalog /share -> /jitsi-meet
Customize Jitsi.png
Here you can select the element you want to change. Press F4 to edit.

Hands-on assignments

Hands-on assignments that CNM learners can use to get accustomed to the software while using its hands-on training systems and applications.

Presentations

CNM WordPress was presented at a series of events called CNMCyber Guided Tours and CNM Technology Board:

User group

CNM Social user group has not yet been created; the group may organize software-related events and produce newsletters.

Architecture

The App is a BigBlueButton instance that is run on the CNM Farms on a separate server.

Server requirements

The minimum server requirements for installing BigBlueButton 1.1 are:
  1. Ubuntu 16.04 64-bit OS;
  2. 4 GB of memory with swap enabled (8 GB of memory is better);
  3. Quad-core 2.6 GHZ CPU (or faster);
  4. TCP ports 80, 443, and 1935 are accessible;
  5. TCP port 7443 is accessible if you intend to configure SSL (recommended), otherwise port 5066 is Accessible;
  6. UDP ports 16384 - 32768 are accessible;
  7. Port 80 is not in use by another application.
Additional requirements are:
  • 500G of free disk space (or more) for recordings;
  • 100 Mbits / Sec bandwidth (symmetrical);
  • Dedicated (bare metal) hardware (not virtualized)
